HINGE.

Application filed May. 13,

To all 'whom t may concern Be it known thatl, .l'oirrN J. Sinni, Jr., aV citizen of' the United States, residing at Elmhurst, in the county of Queens and State of New York, have invented certain new and useful Improvements in lilinges, of which the following is a. full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same. e y

This invention relates to hinge construction, and more particularly to such construe tion designed for mounting swinging doors.

lltis an object of the invention to provide ahinge of improved construction for mounting doors, having readily detachable sec tions, thedetaching means whereof is inaccessible from the exterior of the door.

It is a further object to provide an improved hinge for mounting swinging doors whereby the latter cannotbe detached from its hingemounting from a point to the exi terior thereof while being readily detachable c from an interior point.

A further object is to provide an improved `hinge structure of the class mentioned havf ing readily detachable parts, and which is easily applied and durable andeflicient in luse. y

Often in buildings o-r other compartments where it is desirable to protect the interior from unauthorized access, hinged closures are frequently employed being provided with ample locking means for securing the closure in closed position. The hinge mounting in such cases has proved to be a weak point for attack, and forcible or unauthorized entry has been frequently accomplished by disconnecting or breaking the hinge pints.` Entry is thus frequently gained in spite of the fact that the door lock proved eflicacious to perform its functions. This invention renders it practically impos sible to detach the stationary and movable hinge elements from each other from the outside of an outwardly swinging door while providing means whereby they may be readily detached from a point within, and the door quickly and easily removed lfrom its mountings without the use of special tools. The door is also as readily mounted again in its hinged position in the door frame.

' The invention accordingly consists in the `features of construction,combinations of elements, and arrangement of parts which will 192i. serial No. 469,358.

be exemplified in the construction hereinafter set forth, and the scope of the appli" cation of which will be "indicated in the following claims.

In the accompanying drawing wherein an illustrative `embodiment of the invention is disclosed,

Figure l` is a perspective fragmentary view showing an outwardly swinging door mounted in accordance with this invention;4

` 2 is a fragmentary elevation of one part of the improved hinge mounted in position on the door;

v Fig. 3 is anelevation of a. complementary part of the hinge mounted Ion the door post; and i 5 Fig, l is a transverse sectional view of the hinge.

Referring` to the dra-wing for a detailed description, the door post or `frame is indicated at 1 and outwardly swinging door at 2. It will be understood that the compartment closed by the door is located at the right of the door post asviewed in Fig. l. As many improved hinge units as desired may be employed for mounting a door, but as all units are of the same construction, disclosureof one willfsuflice. vThe hinge butt or section 3 is secured to the edge of the door as by screws, being inset the thickness thereof into the edge of the door which is rabbeted for this purpose. The section 3 is provided at one edge adja cent they outward face of the door with spaced cylindrical lugsor knuckles Ll, provided `with 'central apertures for receiving the securing pin 5, the knuckles being olfset or bent slightly away from the edge of the door asV indicated at 6 in Figui for a. purpose which will clearly appear herein-v after. A complementary butt or section 7 is firmly secured to the door post and has spaced cylindrical knuckles 8 at one edge corresponding to knuckles 4 andwhich in use aredisposed adjacent the inner surface of the door post. The section 7 is also provided at its top and bottom edges with integral flanges 9 bent from the body thereof toward each other into a plane spaced from the body section, providing channels or grooves l0. t

An intermediate hinge section ll is adapted to be pivoted to the door section4 3 being supplied for this purpose at one edgewith knuckles 'i9 adapted to alternate malignment with the knuckles l. rlhe intermediate section is permanently pivotally connected to the door section by the pin 5 passing through the aligning openings in the knuckles and headed at both ends as at 5 to prevent removal. At the opposite edge, section 7 is provided with lugs or knuckles 13 adapted to align in alternate positions with the knuckles 8 of section 7 and to` b e detachably secured thereto by a removable pin i4.

The intermediate section ll isadapted to slidably engage at its upper and lower edges in channels l0 formed by the flanges 9, and is thereby firmly supported in (zo-operative relationship with section 7.

It will be noted that the sectiony or butt 7 is-rabbeted into the face of the door post bringing the pivot pin 5 inwardly beyond said face. The pin,` 5 is alsoy set` inwardly from the outward face of the door post as shown in Figure 4. This arrangement prevents removal of the pin 5 when hinge is mounted inl position due to the overlying projections or shoulders l5 of the door` post. Since the pin 5 is only removable by movement in the direction of itslength, it will be seen that it cannot be removed. without chiselling away the shoulders l5 of the door post aswell as a. considerable portion of the latter to permitl the pinto move longitudinally. This will be particularly difficult of accomplishment particularly if. the-door post is of. meta-l or other hard material. Also it will be noted that the. pin 5 cannot be reached` by 'a hack saw or similar cutting tool for. the reason that it lies inwardly of the surface of the door post.

To prevent binding of the door in open or closed positions, and to permit swinging through 1800, the knuckles 4iareioffset as at G to bring them into. alignment with the knuckles on the section 1l which is slightly spaced from the section 3 asclearly shown on Fig. t. The door is shown in closed position in full lines and in open` position in dotted lines of this figure.

t will be readily perceived from the above disclosure that the door sectionof the hinge is supported through the intermediate sectionl ll., the latter being firmly andimmovably secured to the other hingelsection bv flanges 9 and pin lsf. rlhis connectioiris practically as firm and rigid as an integral connection and functions to support the swinging door in a thoroughly. satisfactory manner. rlhe pivot pin 5 being inaccessible when the hinge is in operative position, and moreover being permanently headed, unauthorized removal thereof, or `the separation of the hinge sections is practically impossible, while at the same time the door is readily removable from its mountings from within by authorized persons merely byremoving pin 14:.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting. sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, av matter of language, might besaid to fall therebetween.

Having described my invention what l claim as new and desire to secure by Letters Patent is l. The combination with an outwardly swinging door and a supporting door post therefor, of a hinge for mounting the door to swing outwardly, including a sect-ion to be secured to the door and a section to be secured to the. door post, means for detachably securing said sections together, said securing means including an intermediate hinge section having a pivotal connect-ion with one of. said rst mentioned hinge sections, said pivotal connection being inset into the hinge mounting to protect it from access from without when the door is in closed position.

2. The combination with an outwardly swinging door and a supporting door post therefor, of a hinge for mounting the door to swing outwardly, including a` section to be secured tothe door and a section to be secured tol the door post, means for detachably securing said sections together, said securing means including an intermediate hinge section having a pivotal connection with one of said first mentioned hinge scctions, said pivotal connection being inset into thehinge mounting to protectit from access from without when the door is in closed position, and said intermediate section having a detachable connection with one of the other sections disposed inwardly from the outer plan of the door post protected from access without when the door is closed but being accessible for detachment from within so that the door may be readily removed from its support by separation of the hinge sections.

3. The combination with an outwardly swinging door and a supporting door post therefor, of a` hinge for mountin o' the door to swing outwardly, including afsectiony to be secured to the door and a section to be secured to the door post, means for 'detachably securing said sect-ions together, said securing means including` an intermediate hinge section having a pivotal connection with one of said firstmentioned hinge secllU tions,said pivotal connection being inset into lugs and being protected froin access from without when the door is closed but being accessible for detachainent from within, so that the door may be readily disengaged from its support upon rein-oval of said securing pin.

4. A hinge for outwardly swinging doors having sections permanently pivotally connected together on a lin-e lying inwardly of the outer surface of the 'door post, so the door may swing outwardly while the pivotal connection between said hinge sections is protected from access from without and means spaced inwardly from said pivotal connection for detachably connecting said sections together.

5. The combination with an outwardly swinging door and a supporting door post theretoig-of a hinge :Eo-r mounting the door for swinging movement having sections with knucklesfor pivotally connecting them together, a pivot pin connecting said knuckles and disposed inwardly of the outer surfaces of the door post so as to obstruct removal of the pivot pin, the knuckles of one section being otfset so as to align withthe knuckles on the other section, and connecting means spaced inwardly from said pivot pin for detachably connecting said sections together.

In testimony whereof I affix my signature, in the presence of two` witnesses.
